Abstract
This paper described new welding process on the L360QS/316L clad pipe with size of Ø355.6mm ×(10+3) mm. Firstly, it adopted TIG welding to conduct overlaying on the pipe end, and then, using TIG welding process for butt welding with argon gas protection. The tensile strength, charpy impact test, hardness, intergranular corrosion test and SCC were carried out to study the properties of the circumferential weld. The results indicated that the welded joint performance of the circumferential weld is good; it is with resistance to intergranular corrosion and stress corrosion. The overlay welding layer plays a good role in isolation function to ensure the weld quality.关键词
